GSL-1700X-II-VT-AF Vertical Tube Furnace for Powder Spheroidization with 1700°C Max Temperature and Dual Heating Zones
The GSL-1700X-II-VT-AF is engineered to convert loose powders into spherical particles by sintering them as they pass vertically through a heated tube. This process is conducted under vacuum or a controlled atmosphere to ensure precise material properties and prevent oxidation. The system is particularly suited for applications involving battery electrode powders, metallic powders used in additive manufacturing, and certain magnetic powders requiring spheroidization.
Powder is automatically fed from the top hopper, travels downward by gravity through a dual-zone vertical tube furnace, and is collected at the bottom after spheroidization. Each heating zone is independently controlled, allowing precise temperature management up to 1700°C with ±1°C stability. The alumina processing tube is high purity (>99.5%) and designed for high-temperature operation, though it is consumable and replaceable.
Wichtigste Merkmale
- Automatic powder feeder with stainless steel hopper and vibrator for consistent delivery, adjustable up to 97 cm³/min.
- Dual independent heating zones, each 200 mm long, with PID controllers and auto-tune for precise temperature control.
- Maximum operating temperature of 1700°C per zone with ±1°C accuracy, monitored by two B-type thermocouples.
- High purity alumina tube (60 mm OD x 54 mm ID x 1200 mm length) for processing, designed for vacuum and controlled atmosphere use.
- Vacuum-sealed system with flanges, including gas inlet needle valve and electric gate valve for powder collection.
- Optional accessories include vacuum pumps, oxygen monitoring sensors, gas purification and circulation systems, hermetic quenching tanks, and PC control software with laptop.
- Power supply: Single phase 208–240 VAC, 50/60 Hz, 7 kW furnace power; powder feeder powered at 200 W.

Typische Anwendungsbereiche
This furnace system is optimized for spheroidizing powders used in battery electrodes, enhancing powder flow and packing density. It also supports metallic powders for additive manufacturing (3D printing) and magnetic powders requiring controlled sintering to achieve spherical morphology.
Hinweise zur Konfiguration und zum Betrieb
The system includes a stainless steel hopper with vibrator and a long feed screw for efficient powder delivery. The alumina tube is consumable and should be replaced as needed. Operation under vacuum or controlled atmosphere requires appropriate vacuum pumps and gas control accessories, which are optional. Oxygen monitoring and gas purification systems are available to maintain low oxygen and moisture levels. A hermetic quenching tank can be added for air-sensitive materials to enable quenching under controlled atmosphere. For safe gas operation, a two-stage pressure regulator must be installed to limit gas pressure below 3 PSI. The furnace is designed for low positive pressure operation below 0.2 bar and gas flow rates under 200 ml/min to prevent thermal shock to the tube. PC control software and laptop are optional for advanced temperature profile management.
